2 10 G fiber ports wont connect on reboot.

OldSchool

I have a sg310 with 1 copper 1000 connection and 2 10G fiber connections to the main swith

they are link Aggregation to the switch with LACP enable on those 3 ports in the switch.

when I reboot the firewall, the 2 10G ports wont connect to the switch and we are dead in the water.

I go unplug the 2 fiber cables, then ping the firewall a couple times, the copper line sees me, then i reconnect the fiber cables and life is good.

ideas?

  • it's not a good idea to mix different speed or media-types within LACP.

    most vendors don't allow this.

    possible you have a LACP trunc and a single link at the same time.

    try to use/connect only the 10GB links.

    check the LACP interface information at the switch.

    Ive tried that.. on the UTM425 i had 1G copper and 1G fiber LACP to the same switch no issues..

    When I tried to move to the fiber ONLY, i lost contact to the UTM.

    It seems that the UTM has to keep the first connection (copper) that I set up as the main connection to the switch. 

    i havent tried that with the SG310, but the 425 was a restore from back up to get it back running..
